Samsung PC3200 Cas 2.5, help needed.

I have a 512mb strip of Samsung PC3200 Cas 2.5 DDR memory

In Sisoft Sandra benchmark my benchmark compared to the PC3200 in Sisoft Sandra is a lot lower score. Why would that be?

I am running my Memory at 3-3-6-3. I have tried running at 2-2-5-2, but it creates a registry error, and I had to format my Harddrive. I guess I have crappy memory?

Got a screenshot? It sounds a pretty low score.

Your memory timings should be set a lot faster too.....I run my Crucial PC2100 at 166MHz 7-1-1-1R 4-1-1-1R 2.0-2-2 1CMD with 4-way interleaving.



Also bear in mind that the Sandra benchie score depends on CPU, FSB, and chipset type.......

Nope..certainly ain't a crappy memory..samsung doesn't like aggresive timings...
Try SPD timings 1st.... i could get my 256 samsung ddr 333 up to 200 fsb with 2 -3-5-3-2 2T command at 2.85v
u need to do some burning in first onto the ram

Btw ur using Tcc4 chipsets for samsung ddr 400?
check out my review on the samsung ddr 400 Tcc4 :

cant you run it at cas 2.5 your memory is rated to do so, if it dosn't allow you to run it like that then you should RMA it

Agressive it ain't, but...

...it does OC with SPD timings

I couldn't get my stick to do much @2.0-2-2-5, but with SPD timings (2.5-3-3-7)
it OCs to 426Mhz w/o overvolting.

It may not sound like much of a OC triumph, but the extra 26MHz certainly helped out
my 3DMark2001SE as well as Sandra memory scores!

I hit the 12000 club (& that w/o pushing the CPU), and Sandra 2003.1.9.26 benched
3139/Int, 3115/fpu

btw, my stick is appearantly provided by some third-party German firm called PowerRam.
However, not only do the chips sport the correct id, but Sandra shows even the
correct Samsung module id (M368L3223DTM-CC4).

Also of interest, Samsung's own spec sheet classifies CC4 as CL3, not CL2.5.

It's not Corsair, but I'm certain that with a little overvolting you can take it higher.

cu,


P.S. (aka edit): Runs stable @162FSBx1.33x2=431MHz as well
However, both 3DMark & Sandra scores only increased by about 50 units: Doesn't seem worth it....

P.P.S. (aka 2nd edit): Runs stable @164FSBx1.33x2=436MHz!
Sandra @3242/3143 - closest I'll get to PC3500 'till I get a better CPU cooler!
btw, I forgot to turn on my aux. case fans - memory hit 50C!!!.
Don't know 'bout you, but that's my all-time heat record I have a single-sided module &
I added a heat spreader & attached a thermal probe to the Hspreader. With aux.
fans on, temp maxes out @44C. Goes to show you how critical good case cooling is
